Be it known that 1, CHARLES E. ONGLEY, a l citizen of the United States, and a resident of the borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Button-Sewing Attachments for Sewing- Machines, of which the following is a specification.

This invention relates to a button-sewing: attachment for sewing-machines. Its object is to provide a device of this character or removed from a sewing-machine.

In the drawings, Figure 1 1s a side View,

invention attached to a sewin n1ac 'ne.

1. Fig. 3 is a plan View of the device shown in Fig. 1. Fig. 4 represents a right-hand end view of-Fig. 1. Fig. 5 shows a section of Fig. Fig. 6 is an end view and partial section of Fig.3 on the line 6 6.

The bed-plate of a sewing-machine is shown at 10, with the arm of the machine at 11, needle bar 12, and needle 13. On the bed-plate 10 fastened with screws 14 the bottom plate 15 of 'thedevice. A'boss 16 extends up from theplate. 15 and has secured thereto the journal-pin 17, on which latter is journaled the link 18. The link 18 carries the pin 19, to which is lnlcrumedthe arm 20. 1 From the plate 15 extends the boss 21, into which is screwed the join'nal-pin 22, and on the latter jonrnaled a ratchet-wheel 23, which carries the guides 24 for an adjustable nut 25. Into the nut screwed the journalpin 26, which carries one end of the arm 20.

A spring 50 is fastened to a lug 51, exlendl ing from the bottom plate, and bears against one end olthe guides 24. A lug 27 extends up from the plate 15 and carries a pin 28, on which journaled a bell-crank with the arms 29 and 30. The end of the arm 29 carries the hollow sphere 31, which, with the ball 32,

ball 31 is attached thepawl 33, the end of whiehengages with the ratchet-wheel 23. On the front side 01' the pawl 33 is fastened the spring34, which bears against the guide 35. The arm of the bell-crank has the tion on the needle-bar 12.

The swinging arm 20 is'doveta'iled for the adjustable jaws 39,.tl1at carry supportingsprings '40, in which are formed pockets 41 for supporting a button 42. support 43 extends from the arm 20. 'A screw with right-hand threads 44 and left-hand A stationary threads 45 is supported and arranged to ro- 'tate in the support 43, a pin 46 engaging with a groove turned in the bodyof the screw at about its middle portion.- The jaws 39 are threaded to receive the threads of the screw and a removable cap 47v is fastened to the screw, as shown.

To 0 erate the invention the aws 39 are set at the proper distance apart, so that the and the pin 26 is made to clamp the nut 25 in the guides 24 to obtain the requisite distance of the axis of the pin 26 from the axis'of the ratchet-wheel 21 to give the proper throw to the arm 20. When the sewing-machine is started, the needle-bar will cause the oscillation of the bell-crank with the arms 29 and 30. The pawl 33 will intermittently rotate the ratchet-wheel 23, which will move. the

'right-hand end of the arm in acircular path,

which motionwill also be obtained for-the button 42, thereby placing it at the proper times under the needle, so that the latter, with its thread,can enter and pass through the openings in the same.

The spring 34 maintains the pawl 33 in en gagement with the ratchet-wheel 23, andthe spring 50 maintains the ratchet-wheel in proper position when the pawl is traveling upon the same.

Having described my invention, I claim 1. In a button-sewing attachment for a sewing-1nachine the combination of a plate, a link journaled on. the plate, a ratchetwheel journaled'on the plate, a pin adjustably connected with the ratchetm'heel, a swinging arm tulcrumed to the said link, one end of the arm journaled to the pin connected with the ratchet-wheel, adjustable jaws connected to the other end of the arm, and means to turntlie ratchet-wheel.

2, In a button-sewing attachment for sewing-machines the combination of a plate,

means to fasten the plate in position on the jaws arranged to he. adjustahly held on the ew:ng-maslnne, a link joilll'lzllfid on the plate, a iat-zzhetqvheel joinnaled to the plate,

a pin adjustably eonneeted with the ratchet wheel, a Swinging a'ri'i'i fulerinned to said link, one end of the arm join'naled on the pin 5 extending from the ratsl'iet-wheel, adjust-Q ahle jaws extending from the OtllQl end of the arm, a lug extending from the plate, a hellcrank journaled from the upper end of the lug, one arm of the bell-erankconneeted with the needle-bar, the other'end ofthe hellcrank carrying a pawl and th'e'pawl arranged to engage with the ratchet-Wheel.

in a button-sewing attachment for a sewing-machine the combination of a hot-tom jilate attached to the bed of the machine, a

ink journaled to the bottom plate, a swing-- ing arm fulerumed to-the said link, a ratchetwheel onrn'aled to the bottom plate,'gu1des extending from the ratehet-WheeL-a nut loeated in the said guide, a pin s e red into the 'nut to clamp the nut in ditl'erent positions in the guides, one end of the swinging arm journaled on the pin extending from the said nut,

other end ol the arm, a. support extending from the "mm between the latter jaws, a szrew with a righthanded and a left-handed thtead held in said support, the screw engaging threads in the adjustable jaws on the arm, spring-jaws eom'ieeted with the said adjustable jaws to hold a button, a lug tending up from the hot-tom plate, a hellci'ai'ik jOUlDELlGLl to the latter lug, an arm of the hell-crank having a naked end. connected with the needle-ha! of the mael'iine, the sec;- ond ai'm having a pawlconnected therewith, a hail-and-soaket oint eonneeting the al'nioi' the hell-erank and paw], a spring attaehed to the pawl, and a guide for" the spring, to maintain the pawl in engagvmei'it with the ratzrhet-whe'ei.
